执行Segue后事情不起作用

Question

I have the following problem: I have a ViewController with an UIScrollView and an UICollectionView in it. When I launch the App directly at this View Controller, everything works fine. When I call the ViewController, from another ViewController (here it is a Google Maps SDK Map), the ViewController loads, but when I try to scroll I get this Message, and the App stops:

*** -[TheSecondViewController respondsToSelector:]: message sent to deallocated instance 0x16ef3890

Here is some more code: Calling the view:

-(void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker {

     [self performSegueWithIdentifier:@"OpenSecondView" sender:self];

}

viewDidLoad in the secondView:

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view.

    if (IS_IPHONE5) {

        self.scrollV.frame = CGRectMake(0, 0, 320, 568);
        NSLog(@"Das Geraet ist ein iPhone 5 / iPhone 5S");

    } else {

        self.scrollV.frame = CGRectMake(0, 0, 320, 480);
        NSLog(@"Das Geraet ist ein iPhone 4 / iPhone 4S");

    }

    [self.view bringSubviewToFront:scrollV];

    [scrollV setScrollEnabled:YES];
    [scrollV setDelegate:self];
    [scrollV setContentSize:CGSizeMake(320, 833)];
    [collectionV setScrollEnabled:NO];

    activityInd.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;

    [activityInd startAnimating];

    [imageView setUserInteractionEnabled:YES];

}

Knowing that you have just loaded the secondViewController, it looks like your secondViewController is not allocated properly(rather than being deallocated). Try using segues that are created in storyboard and calling those segues with code, and/or using strong instead of weak references to your view
